Question

warm-up #1
find the mean, median, mode and range.
7 5 6 15 4
9 10 1 12 8
13 7 11 6 10

Explanation:

Step1: List all data values

$1, 4, 5, 7, 7, 8, 8, 8, 9, 10, 10, 11, 12, 13, 15$

Step2: Calculate the mean

Sum values: $1+4+5+7+7+8+8+8+9+10+10+11+12+13+15 = 126$
Mean: $\frac{126}{15} = 8.4$

Step3: Find the median

Middle value (8th term): $8$

Step4: Identify the mode

Most frequent value: $8$

Step5: Calculate the range

Max - Min: $15 - 1 = 14$

Answer:

Mean: $8.4$, Median: $8$, Mode: $8$, Range: $14$
